论文摘要
在Tio 2（110）上生长的Au-cu双金属纳米颗粒（NP）已使用放牧发射率X射线衍射和X射线光发射光谱从其合成中接触到低压下的CO/O 2混合物（P <10-5 MBAR）和不同温度（P <10-5 MBAR）和不同的温度（300 k-470 K-470 K-470 K-470 K-470 K-470）。准备的样品由两种类型的合金NP组成：随机定向和
Au-Cu bimetallic nanoparticles (NPs) grown on TiO 2 (110) have been followed in-situ using grazing incidence x-ray diffraction and x-ray photoemission spectroscopy from their synthesis to their exposure to a CO/O 2 mixture at low pressure (P < 10-5 mbar) and at different temperatures (300 K-470 K). As-prepared samples are composed of two types of alloyed NPs: randomly oriented and
